AI Engineering from Scratch

A free, hands-on curriculum that teaches AI engineering by building models, search systems and agents yourself.

Fast-rising

What it does

This is a large, free course on building AI systems, organised into phases and learning paths, from setup and maths foundations through language models to AI agents.

Lessons can be read on the project's website, followed with a coding agent, or run as code on your own computer. It includes projects with starter code and automatic graders that check your work, using Python, TypeScript, Rust and Julia. The lessons are offered in many languages.

Who it's for

People learning to become AI engineers, especially those comfortable with some programming.

Can I use it without coding?

Yes. The lessons can be read on the website; the projects need programming tools. New to this? Start here.
